My Zero AUW is 17.2~17.5Lbs mainly due to scratch built strong wing and fuselage repairs after crash.
(CG 135~140mm at the root, sure little tail heavy)
Today I flew few times and my wife took some video by new camera I bought.
It was first time today for her use this camera (Canon powershot SX130) so sorry for not catching up the speed...
I think 17.5Lbs CMP zero 71" flies pretty good but landing is little challenge everytime to not to damage retracts..
I got dead stick few weeks ago with this 17.5Lbs zero and luckly came back to ground with no issue. (Of course I was very nervous and just tried not to pull elevator at all until wheels touch to the ground).
These are the videos I uploaded today.
